I finished repairing the adapter.
Then I put in the new module. (on the right)
So here's the thing with this 5-pin module. They were only used for a few years, around 1978-80 or so. The fifth pin would be grounded while cranking, to retard the timing 10 degrees, to make it easier to start. So now you can get one of these, run a wire from it to a pressure switch, and when you hit the desired pressure, it ******* the timing. Bam, a $30 boost ignition retarder.
So, I found out about this online, and the guy that used it, had it on a four cylinder. He only got 5 degrees out of it. So I thought with a six cylinder, maybe I'd get 7.5 degrees, maybe. It turns out that I get 16.5 degrees of retard with this one. I don't know what to make of it all, but I'm not too concerned. I just won't be using that part of it if I can't figure out what's wrong.
I also bought a Mr Gasket (Holley) advance kit with weights and springs. Everything I read online said to just throw the weights and center plate away, and use the springs on the old weights. Well, why wouldn't the new weights work better? They don't. The kit was awful, terrible even. First of all, it advanced my initial timing 22 degrees, on top of the 4 I already had. So I turned it down to 4 again, and started mapping the curve.
The weights interfere with each other, and it wouldn't advance at all, until about 1500 RPM, then it would jump about 4 degrees. I'll spare you all the rest, but I ground the tips off the weights, to make them swing free, and tried all the different springs. Oh, I almost forgot, I had to drill out the holes on the center plate, about .010" each, to even get the thing on, and it was still a press fit. Then, for the first couple hundred of RPM increase, it was actually retarding the spark about two degrees.
So the fancy weights would only advance 8 degrees, and it was in steps. Then it would hold a given advance for about 300 RPM lower, on the deceleration side.
Total junk.
The old weights advance 19 degrees. So, old weights and new springs it is.
I know this may not be thrilling reading, but after spending a long time looking for information online, and finding very little, I thought someone might like the info.
